  • Publication number: 20240383250
    Abstract: An inkjet recording device includes a conveyance unit, a carriage, one or a plurality of ink heads, a pre-processing head, and a post-processing head. The conveyance unit is configured to convey a recording medium in a conveyance direction. The carriage is configured to reciprocate in a main scanning direction intersecting the conveyance direction. The plurality of ink heads is located on the carriage and each eject an ink. The pre-processing head is arranged upstream of the plurality of ink heads in the conveyance direction and ejects a non-colored pre-processing solution. The post-processing head is arranged downstream of the plurality of ink heads in the conveyance direction and ejects a non-colored post-processing solution. The plurality of ink heads includes a plurality of same-color ink heads arranged to align in the conveyance direction to eject a same-color ink.

  • Patent number: 9208546
    Abstract: An image processing apparatus includes an extraction section that extracts a first high brightness region from a source image where brightness is a first threshold value or greater, a mask generation section that performs blur processing and binarization processing on the first high brightness region and generates a mask containing the first high brightness region, a mask application section that based on the mask performs elimination processing, thinning processing, or both on the first high brightness region, a bright line generation section that generates a bright line based on a second high brightness region contained in output of the mask application section, and a synthesizing section that synthesizes the bright line onto the source image.
